I Tested And Reviewed 10 Best Smart Thermostat For Mini Split (2023)

The thermostat I purchased had a few positive features that I really liked. First of all, the setup process was incredibly easy. I didn't have to spend hours trying to figure out complicated instructions or dealing with confusing settings. Additionally, the price of the thermostat was great. It was affordable and didn't break the bank, which was a huge plus for me.

However, I did have a few concerns with the thermostat. One issue I encountered was that the manual that came with it was printed in a very small font. This made it difficult for me to read and understand the instructions properly. Another drawback was that I had no control over the air swing and louvre direction. It would have been nice to be able to adjust these settings according to my preferences.

Furthermore, I found that the thermostat wasn't really set up for Fahrenheit measurements. Everything was converted to Celsius, which was a bit inconvenient for me as I am used to Fahrenheit. It would have been more user-friendly if there was an option to switch between the two measurement systems.

I recently purchased two Cielo Breez Plus devices and I couldn't be happier with my purchase. The delivery was prompt and the items were well-packaged, ensuring that they arrived in perfect condition. Setting up the devices was a breeze, with the included cable and USB charger making the process quick and easy. I particularly appreciated the desk mount/stand and wall mount options, giving me flexibility in where to place the devices.

Creating a profile on the Ceilo app was a seamless experience. Connecting my phone to the Cielo device's WiFi was straightforward, and the app guided me through the process of connecting to my home WiFi network. Within minutes, I had one of the devices up and running, connected to my AC/Heat Pump unit. The app's instructions were clear and concise, and I was able to configure the device with ease. Testing the functions from the app, the Cielo Breez Plus device, and the original remote all worked perfectly.

Setting up the second device was just as simple as the first. Downloading the app on my wife's phone and logging into Cielo allowed the two AC/Heat Pump units to immediately show up in the app. The seamless integration between devices was impressive.

I also wanted to enable Amazon Alexa to work with the Cielo Smart Home. Linking my Cielo account to the Alexa Smart Home Skill was a quick process, and the devices were automatically discovered. However, I did encounter a minor issue with the device names. I had named the devices with "shop" at the end, but Alexa didn't recognize them with the spaces. After renaming the devices without spaces, they worked flawlessly with Alexa.

From the purchasing process to the final operation, I give the Cielo Breez Plus a solid 5-star rating. I would highly recommend it to anyone looking for a remote control solution for their AC/Heat Pump.

The sensor is a great addition to any setup, as it offers a wide range of functionality. It is worth noting that it requires a USB connection for power, which may be a downside for some users.

I cannot praise the Cielo Breez Max enough. This device has transformed my mini split into a smart unit, allowing me to control it remotely from my phone. Not only does it function as a traditional thermostat, but it also provides the convenience of remote app control. Cielo has truly outdone themselves with this upgraded model, and I highly recommend it to anyone looking to transform their AC/split unit or heat pump into a smart unit.

Previously, I had a Fujitsu mini-split installed and was in need of a wifi thermostat with a remote app. However, Fujitsu's price for their wifi thermostat was exorbitant, costing over $400. That's when I discovered the Cielo Breez Max, which was not only affordable but also available in a white color that pleased my wife.

The installation process was straightforward, and I had already run a wire to connect the Breez Max to a 24-volt transformer. Initially, there was a discrepancy in fan speeds between the Cielo app and the mini-split. However, I reached out to Cielo's tech support, and I was astounded by the quality and patience they displayed. They were able to capture the Fujitsu's remote command sequence using the Breez Max installed on my wall and then relayed that information to their programmers. Their ability to resolve this issue was truly impressive.

The tech support team informed me that they would contact me in a couple of days with updated firmware to rectify the fan speed problem. True to their word, they called me back, and during the phone call, we updated the firmware for the Breez Max, resulting in the fan speeds matching those of the Fujitsu remote. As someone with experience in technology and tech support, I can confidently say that Cielo handles their product support exceptionally well. I wish every company provided the same level of support as Cielo does.

I must admit, I was skeptical about the possibility of turning old AC units into smart units. However, when my family decided to venture into short-term rentals, I realized the need for a solution. Our house, built in 1860, lacked central air, and the cost of installing it was astronomical considering we were already furnishing the entire house. However, with the Cielo Breez Max, everything changed for the better.

We installed this device on used AC units, and it not only functions as a thermostat in each room but also allows our guests to easily control the temperature. Moreover, we can monitor the units, set restrictions, and even turn them off remotely once guests have checked out, all from the comfort of our own home. Additionally, for units where we had misplaced or didn't have remotes, this device provides an easy way for guests and ourselves to adjust the temperature and schedule.

Setting up the Cielo Breez Max required a phone call, but the customer service I received was top-notch. They promptly connected me and assisted me in getting everything up and running in under 10 minutes. I was truly amazed when the unit was connected, and I gained the ability to control it from my phone. It's astonishing how this device can update older AC units, providing a modern and refined look while enhancing their functionality.

I recently upgraded my home's thermostat with the Nest smart thermostat, and I must say, it has been a game-changer. Our house, built in 2003, still had the original furnace, but the Google compatibility test assured us that the Nest would work seamlessly. I eagerly pre-ordered it and received it promptly after the launch.

The installation process was a breeze thanks to the user-friendly Google Home app. It provided clear step-by-step instructions, ensuring that even someone like me, with limited technical skills, could easily set it up. However, I did encounter a minor issue when I realized that our old thermostat didn't have a C (common) wire. Three wires were left unconnected, both at the thermostat and the furnace. After a quick visit to the furnace in the garage, I successfully connected one of the unused wires to the C wire on both ends. Voila! The C wire was recognized, and the Nest received constant power.

One of the standout features of the Nest is its sleek design. The Home Screen displays useful information such as the date, time, indoor/outdoor temperature, and humidity. It integrates seamlessly with my Alexa Dot, allowing me to control it effortlessly. The Nest fulfills all our needs and functions flawlessly.

I would also like to highlight the cost-saving aspect of this smart thermostat. Within just two weeks of installation, it already proved its worth. I received a notification from the Nest informing me that my furnace had unexpectedly turned off multiple times. Upon investigation, I discovered that the previous homeowner had neglected to change the air filter, causing a significant airflow issue. Thanks to the Nest's warning, I was able to rectify the problem by simply replacing the filter, preventing potential furnace failure. I highly recommend this thermostat for its ability to detect and alert you to potential issues, saving you from costly repairs down the line.

In addition to its functionality, the Nest also offers potential rebates from gas/electric providers. I would suggest checking with your provider, as we were fortunate enough to receive a $75 rebate for purchasing a smart thermostat.

We installed the Nest after our previous manual smart thermostat failed, and it has exceeded our expectations. Currently, we are using it for our upstairs, which is not frequently visited as empty-nesters. Not only have we noticed a significant drop in our power bill, but we can also set the comfort settings to ensure a cozy atmosphere whenever we do use the upstairs area.

The Ambi Climate device is a great addition to any home with mini-split air conditioning units. It offers easy setup, allowing you to use your existing remote controller. However, it should be noted that it only controls the basic modes and not the lesser important features of the remote.

One of the standout features of the Ambi Climate is its compatibility with smart home systems like Alexa. This allows you to make changes to the temperature settings using voice commands, providing convenience and ease of use. The AI features of the app also learn your habits and preferences, adjusting the temperature accordingly.

The app itself provides a wealth of information and analytics about current and historical conditions, giving you a better understanding of your indoor environment. This is particularly useful for maintaining a constant temperature as recommended by Mitsubishi.

Installation is straightforward, with clear online instructions. In some cases, a manual installation may be required for older mini-split units, but it is still a simple process.

Many users have found the Ambi Climate to be a game changer, especially for areas that are difficult to heat or cool with regular AC units. It allows remote control and scheduling of temperature changes, eliminating the need for wasteful constant temperature settings or manual adjustments.

I recently installed several Cielo controllers in my home to control my Fujitsu mini-splits, and I must say, I am impressed. Not only are they easy to install, but they are also much more affordable compared to similar controllers from Fujitsu.

One of the main reasons I decided to go with Cielo controllers is because of their user-friendly interface and remote accessibility. I can easily control my air conditioning from anywhere, whether I'm at home or away. The controllers offer a range of features that satisfy most owners' requirements for an A/C controller, including Comfy mode and program scheduling.

While it may take a bit of time to fully understand how to utilize all the functionalities, once you grasp it, you can take full advantage of the controllers' capabilities. The integration with Alexa works seamlessly, although there might be instances where Alexa misunderstands a request as a Cielo command. This issue, however, is more related to Alexa than Cielo.

One thing to note is that the Cielo controller does not sync with the original Fujitsu remote. So any changes made using the Fujitsu remote will not be reflected in the Cielo app or controller. I would recommend putting away the original remotes after installing the Cielo controllers to avoid confusion, unless someone in your household prefers using the Fujitsu remote.

The Cielo app is relatively easy to use and serves as the primary control option if your controller does not have physical controls. However, it's convenient to have the option to check the current status of the air conditioning without opening the app by glancing at the controller.

One aspect to consider is the placement of the controller. While you can place it anywhere as long as the transmitters can reach the mini-split unit, keep in mind that the room temperature reading may not accurately reflect the temperature where you are sitting, especially in larger rooms. This is a common issue with temperature sensors in mini-splits as well. Adjusting the set point may be necessary to achieve the desired room temperature.

Lastly, I highly recommend the Cielo controllers. They offer excellent functionality and value for money. The decision ultimately comes down to choosing the controller that best suits your specific requirements.

I purchased the Sensibo device during the Black Friday sale and I must say, it has exceeded my expectations. It seamlessly connected to my old Kenmore windows AC unit and has been functioning perfectly ever since. The features offered by Sensibo are truly impressive. I can check the temperature and humidity levels from anywhere in the world, turn on or off the AC remotely, integrate it with Google Home, and even schedule it to suit my needs. These features have made my life so much more convenient.

However, I do feel that the price of the Sensibo device is a bit high, even with the Black Friday discount. In my opinion, a fair price point would be around $50. Despite this, I still love the convenience and functionality that this device provides.

I would like to provide an update to my initial review. I had some limitations with the device initially, but after reaching out to Sensibo customer support, they worked with me to address the issues. They scheduled a time to go over the missing functions and within a few days, the device was working exactly as I wanted it to. The fact that Sensibo was willing to work with me and ensure that I had a positive experience has made me a happy customer. I am even considering purchasing a second device for another AC unit.

I have been using the Ambi Climate device for a few days now and initially had some doubts. I had previously purchased other remotes with an LCD display, which I found to be great. However, the Ambi Climate does not offer the same readout. Despite this, the device more than makes up for it with its AI feature. The AI feature is truly impressive as it adjusts the room temperature accordingly, resulting in a more comfortable sleep. I have become so accustomed to this device that it will be difficult for me to sleep elsewhere without it controlling my AC.

During the setup process, I encountered some difficulties and reached out to Amazon for support. After going through the basic steps, which I had already tried myself, I was directed to contact the manufacturer. Ambi Climate was fairly responsive through the app's contact module. However, after four days of troubleshooting, it was determined that there was a hardware issue and I was asked to send the device in for repair (shipping cost not covered). Instead, I returned the device through Amazon and ordered a replacement. I will update my review once the replacement arrives.

Update: I received the second unit and was initially disappointed to discover that my AC was not supported natively. However, the customer service from Ambi Climate was excellent. They arranged a call to capture the codes used by my remote and the next day, everything was working perfectly. I highly recommend this product, as long as you are willing to work through the setup process.

The Ambi Climate 2, along with its support staff, does a commendable job of ensuring that my house is at the desired temperature. The AI-based comfort mode is particularly impressive, as it learns my preferences based on my feedback. I can easily indicate whether I feel cold, comfortable, or warm, allowing the device to adjust accordingly. With the help of Ambi support staff, I was also able to integrate Ambi with my Alexa device, enabling me to control the device using voice commands.

One of the best features of the Ambi Climate 2 is the ability to set the temperature lower when I am away and have the heat start kicking in before I return home, all with just a few taps on the app. If I had a predictable schedule, I could even set a timer for this function. The setup process was straightforward, requiring me to simply provide the model number of my remote and let Ambi do the rest. The device successfully detected all the settings of my ductless unit, and any missing settings could be submitted within the app for review and addition.

The Flair Smart Vent system is truly impressive and has exceeded my expectations. Previously, I was considering hiring an HVAC company to rework the ducting and install motorized dampers, a zone controller, and multiple thermostats to create two heating/cooling zones. However, with the Flair Puck and Smart Vent covers, I was able to achieve the same result at a fraction of the cost.

By purchasing one Flair Puck and 14 Flair Smart Vent covers in different sizes, I was able to create individualized temperature zones in each room that had a sensor. The Ecobee thermostat sets the temperature and reads the sensors, while the Flair Puck sends signals to open and close vents, ensuring consistent temperatures throughout the house. Plus, with the Flair app, I can easily adjust the desired temperature in any room.

The Smart Vents themselves are well-made, mostly constructed from metal. They are durable and comparable in quality to the vent covers I was replacing. The vent covers can either run on batteries for several years or be connected to a low-voltage wire, offering flexibility in power options. I found it useful to use plenum wire in older homes where accessing the space above the ceiling or below the floor is challenging, allowing me to run the low-voltage wires directly inside the duct.

In terms of design, I was pleasantly surprised by the compact size of the Flair Puck. It is significantly smaller than the Nest Thermostat, which I appreciate. The e-ink display, although slightly laggy, is a smart choice to conserve electricity when running on batteries. The rotating ring on the Puck could be smoother and more substantial, but it does the job.

While Flair suggests having a Puck in each room for temperature control, I found that one Puck for the entire house sufficed. I primarily use the Ecobee and Flair apps on my phone to manage the temperature. Additionally, I opted for Ecobee SmartSensors, which are more cost-effective than the Flair Pucks.

One important note is that the first Flair Puck acts as the WiFi gateway and hub for the entire system. It needs to be plugged in and cannot run on battery power for extended periods. This means there will be a thin white wire running from an outlet to the Puck, unless you choose to install a low-voltage wire for a cleaner look.

I did thorough research on the radio frequencies used by various smart home devices to ensure they wouldn't interfere with each other. Flair uses a proprietary protocol in the 915 MHz band, and I haven't experienced any conflicts or performance issues with other devices using WiFi, Bluetooth, Z-Wave, or Zigbee. I recommend utilizing WiFi in the 5-6 GHz range to avoid potential interference.

It's worth mentioning that Flair Smart Vents are now available at major retailers like Home Depot and Lowes, indicating that they are ready for mainstream adoption. Overall, I highly recommend the Flair Smart Vent system. It's a fantastic product that offers cost-effective and efficient temperature control for every room in the house. Well done, Flair!
